Built around the concept in “Which acid is present in gastric juice?”, this bilingual General Science item checks whether a learner can connect a scientific term with its exact property, mechanism or function. The verified answer is Hydrochloric acid.
Hydrochloric acid is the scientifically supported answer. Hydrochloric acid in gastric juice helps digestion and kills microbes. A common name, formula, acid-base character or periodic position provides a stronger basis than superficial similarity between substances. The alternatives Sulfuric acid, Nitric acid and Acetic acid are legitimate scientific terms, but each belongs to a different function, property, material or context.

General Science covers basic concepts in Physics, Chemistry, Biology, and Earth Science. It is an important section in competitive exams like SSC CGL, UPSC Prelims, Railway NTPC, and Defence exams. Questions include scientific laws, inventions, human body systems, chemical reactions, and everyday science phenomena. NCERT Science books from Class 6 to 10 are recommended.
Newton's Three Laws of Motion: 1) First Law (Law of Inertia) - An object remains at rest or in uniform motion unless acted upon by an external force. 2) Second Law - Force equals mass times acceleration (F=ma). 3) Third Law - For every action there is an equal and opposite reaction. These laws are fundamental to Physics and frequently asked in SSC CGL, Railway, and NDA exams.
